Fueling the Tractor
• CAUTION: WHEN HANDLING DIESEL FUEL,
OBSERVE THE FOLLOWING:
• DO NOT SMOKE AROUND DIESEL FUEL.
UNDER NO CIRCUMSTANCES SHOULD
GASOLINE, ALCOHOL, GASOHOL OR DIESELHOL
(A MIXTURE OF DIESEL FUEL AND ALCOHOL) BE
ADDED TO DIESEL FUEL BECAUSE OF INCREASED
FIRE OR EXPLOSION RISKS. IN A CLOSED
CONTAINER, SUCH AS A FUEL TANK, THEY ARE
MORE EXPLOSIVE THAN PURE GASOLINE.
DO NOT USE THESE BLENDS. ADDITIONALLY,
DIESELHOL IS NOT APPROVED DUE TO
POSSIBLE INADEQUATE LUBRICATION OF THE
FUEL INJECTION SYSTEM.
• CLEAN THE FILLER CAP AREA AND KEEP IT
FREE OF DEBRIS.
• FILL THE TANKS AT THE END OF EACH DAY TO
REDUCE OVERNIGHT CONDENSATION.
• NEVER TAKE THE CAPS OFF OR REFUEL WITH
THE ENGINE RUNNING.
• KEEP CONTROL OF THE FUEL NOZZLE WHILE
FILLING THE FUEL TANKS.
• DON’T FILL THE TANKS TO CAPACITY. ALLOW
ROOM FOR EXPANSION. IF THE ORIGINAL
FUEL TANK CAPS ARE LOST, REPLACE THEM
WITH BUHLER VERSATILE CAPS AND TIGHTEN
SECURELY.
• WIPE UP SPILLED FUEL IMMEDIATELY.
• USE ONLY INTERNALLY GROUNDED FUELING
HOSE FROM STORAGE TANK AND PUMP TO
TRACTOR FUEL TANK. IF IN DOUBT CHECK WITH
YOUR FUEL HOSE SUPPLIER. (AN ACCEPTABLE
FUEL HOSE WOULD BE ONE WITH AN INTERNAL
WIRE THAT CAN BE CHECKED USING A
CONTINUITY TESTER.)
• WHEN REFUELING, MAKE SURE THE NOZZLE
IS IN CONTACT WITH THE FILLER NECK OF
THE TRACTOR FUEL TANK BEFORE FUEL
STARTS FLOWING AND DURING THE ENTIRE
TIME FUEL IS FLOWING.
Fuel Storage
Take the following precautions to ensure stored fuel is
kept free of dirt, water, and other contaminants .
• Store fuel in black iron tanks, not galvanized tanks,
as the zinc coating will react with the fuel and form
compounds that will contaminate the injection
pump and injectors .
• Install bulk storage tanks away from direct sunlight
and angle them slightly so sediment in the tanks
will settle away from the outlet pipe . Check the fuel
storage tanks regularly for condensation by draining
from the tank bottom .
• To facilitate moisture and sediment removal,
provide a drain plug at the lowest point at the end
opposite the outlet pipe .
• If fuel is not filtered from the storage tank, put a
funnel with a fine mesh screen in the fuel tank
filler neck when refueling .
• Arrange fuel purchases so summer grade fuels are
not held over and used in winter .
• Ground the storage tanks to prevent static
buildup .
Fuel Requirements
The quality of fuel used is an important factor for
dependable performance and satisfactory engine life .
Fuels must be clean, well-refined, and noncorrosive
to fuel system parts . Be sure to use fuel of a known
quality from a reputable supplier .
To obtain optimum combustion and minimum engine
wear, the fuel selected for use should conform to the
application and property requirements outlined in the
following “Diesel Fuel Selection Chart” on page 4-4 .
NOTE: When long periods of idling or cold-weather
conditions below 0° C (32° F) are encountered or when
continuously operating at an altitude above 1,524 m
(5,000’), use Number 1-D fuel.
Using diesel fuel with sulphur content above 0 .50%
requires more frequent oil changes as noted in the
maintenance schedule .
The use of diesel fuel with a sulphur content above
 .3% is not recommended .
